The book written against fame and learning has the author's name on the title-page.

Congratulate yourself if you have done something strange, extravagant and broken the monotony.

It is frivolous to fix pedantically the date of particular inventions. They have all been invented over and over fifty times. Man is the arch machine, of which all these shifts drawn from himself are toy models. He helps himself on each emergency by copying or duplicating his own structure, just so far as then need is.

The man, who has seen the rising moon break out of the clouds at midnight, has been present like an archangel at the creation of light and of the world.

Life itself is ... a sleep within a sleep.

The way to mend the bad world is to create the right world.

Give all to love: Obey thy heart; Friends, kindred, days, Estate, good fame, Plans, credit, and the Muse,- Nothing refuse.
